Introduction of air-cooled chiller
May 17, 2022
Air-cooled chiller: a type of chiller, the water at room temperature is cooled to a certain temperature by the compressor of the condensing unit to strengthen the cooling of the mold or machine, as a stand-alone use, the heat dissipation device is a built-in fan, there are mainly three mutual Contact systems: refrigerant circulation system, water circulation system, electrical automatic control system.
Refrigerant circulation system: The liquid refrigerant in the evaporator absorbs the heat in the water and begins to evaporate, and finally a certain temperature difference is formed between the refrigerant and the water, and the liquid refrigerant is also completely evaporated into a gaseous state, which is then sucked in and compressed by the compressor. (increase in pressure and temperature), the gaseous refrigerant absorbs heat through the condenser and condenses into a liquid. After throttling through the expansion valve (or capillary), it becomes a low temperature and low pressure refrigerant and enters the evaporator to complete the refrigerant cycle process.
Water circulation system: The water pump is responsible for pumping water from the water tank to the equipment that the user needs to cool. The chilled water takes away the heat and then the temperature rises, and then returns to the chilled water tank.
Electrical automatic control system: including power supply part and automatic control part. The power supply part supplies power to compressors, fans, water pumps, etc. through contactors. The automatic control part includes thermostat, pressure protection, delay device, relay, overload protection, etc. to achieve automatic start-stop, protection and other functions according to the water temperature.
